Answer:
y = 936x + 3742
Step-by-step explanation:
If it is a linear model, then we should have a slope and y-intercept with the equation representing the model as;
y = mx + c
where m is the slope and c is the y-intercept
Thus, we have for the slope;
(8422-3742)/(2015-21010) = 4680/5 = 936
So the equation will be;
y = 936x + c
To get c , we can use the years after 2010 which is 2015 in this case
8422 = 936(5) + c
c = 8422- 4680
c = 3742
So the linear model is;
y = 936x + 3742

Three times the difference of a number and 5 is the same as twice the number, decreased by 3. Find the number
Answer:
x = 12
Step-by-step explanation:
3 (x-5) = 2x - 3
3x -15 = 2x - 3
x-15 = -3
x = 12
check:
21 = 21
The number as decribed (Three times the difference of a number and 5 is the same as twice the number, decreased by 3) in the question is; 12
According to the question;
Three times the difference of a number and 5 is the same as twice the number, decreased by 3.The word problem can be written and solved as follows;
3(x - 5) = 2x -33x -15 = 2x -33x -2x = 15 -3x = 12Read more:

In the right ∆ABC, BL is an angle bisector. If LB = 1.2 in and LC = 0.6 in. Find:
- The distance from L to AB.
- m∠ABC
Answer:
Distance of L from AB = 0.6 in.
m∠ABC = 60°
Step-by-step explanation:
Given:
LB = 1.2 in
LC = 0.6 in
We have to find the distance of point L to AB or length of LD.
From right triangle ΔBCL,
Sin(∠LBC) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{LC}{LB}[/tex]
= [tex]\frac{0.6}{1.2}[/tex]
= [tex]\frac{1}{2}[/tex]
m∠LBC = 30° [Since ∠LBC is an acute angle]
Since, ∠LBC ≅ ∠LBA
m∠LBA = 30°
Now from right triangle ΔLDC,
sin(∠LBA) = [tex]\frac{LD}{BL}[/tex]
sin(30)° = [tex]\frac{LD}{1.2}[/tex]
[tex]\frac{1}{2}=\frac{LD}{1.2}[/tex]
LD = 0.6
Therefore, Distance of point L from AB is 0.6 in.
m∠ABC = m∠ABL + m∠LBC
= 30° + 30°
= 60°

-6/3 = x
-2 = x
x = -2
Rita goes for a bike ride on a trail by her house. After 15 minutes of riding she sees a mile marker. When she reaches the third mile marker, she realizes that she has been biking for 30 minutes. What is the rate at which she is riding?
Given:
Rita covered 1 mile in 15 minutes.
She covered 3 miles in 30 minutes.
To find:
The rate at which she is riding.
Solution:
Let y be the number of miles covered in x minutes.
Rita covered 1 mile in 15 minutes. So, the point is (15,1).
She covered 3 miles in 30 minutes. So, the point is (30,3).
Slope of the line:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{3-1}{30-15}[/tex]
[tex]m=\dfrac{2}{15}[/tex]
Therefore, she is riding [tex]\dfrac{2}{15}[/tex] miles per minute.

Mary had $60 and spent .75 of it for a coat. She then bought a skirt with 50%
of the money that she had left. How much money did she have left after buying
the coat and skirt?
The correct answer is She have left $7.5 after buying the coat and skirt.
Step-by-step explanation
This question is incomplete, the complete question is:
Mary had $60 and spent 0.75 o 3/4 of it on a coat. She then bought a skirt with 50% of the money that she had left. How much money did she have left after buying the coat and skirt?
The answer is $7.50
Explanation:
To know how much money Mary has left after buying the coat we have to multiply $60 by 0.75 as this would help us know the price of the coat.
60 x 0.75 = 45 (price of the coat)
Then we have to subtract 45 from 60 to know how much money she have left after buying the coat.
60 -45 = 15 (Money left)
Then she bought a skirt with 50% of the money that she had left. To know how much money costs the skirt we have to multiply 15 by 0.50. The result of this operation is $7.5, and finally, we have to subtract again $7.5 that she spent on her skirt from $15 and the final result is $7.5

Nikki just graduated from high school and would like to buy a car. If she received $3000 in graduation gifts from family friends. She will put this money into a 18 month certificate of deposit until she finds the car of her dreams. The CD earned 10% annually and simple interest. How much will she put towards the down payment and 18 months 1.5 years?
Answer:
$3450
Step-by-step explanation:
Here, P = $3000, N = 1.5 years, R = 10%
[tex]SI = \frac{PNR}{100} \\ \\ SI = \frac{3000 \times 1.5 \times 10}{100} \\ \\ SI = 450 \\ \\ [/tex]
Amount of down payment
= $3000 + $450
= $3450
How to Rewrite 8 + 36 as a product of their GCF and the sum of two factors
Answer:
4 (2 + 9)
Step-by-step explanation:
Given expression:
8 + 36
The greatest common factor is the highest number that divides a number:
8 and 36 ;
Factors of 8 : 1,2,4, 8
36 : 1, 2, 3, 4, 9, 18, 36
The highest common factor is 4;
8 + 36 = 4 (2 + 9)
Solve using fraction strips or common denominators:
1/2 + 3/10=
Answer:
4/5 (or 8/10)
Step-by-step explanation:
the least common denominator of 2 and 10 is 10, so you have to multiply the first fraction (1/2) by 5/5 so that the denominator of that fraction will become 10. Since 3/10 already has 10 as the denominator, you leave it. By adding 5/10 and 3/10 together you'll get 8/10.
If the question asks to simplify your answer, divide the numerator and denominator of 8/10 to get 4/5
